RS232 Interface (XSP Series)

The XSP series (XSP01L, XSP01R, XSP11L, XSP11R) uses the classic serial interface according to RS-232 standard for maximum compatibility with industrial PCs, terminals, and PLC controllers.

Pin Assignment

The module is designed as DCE (Data Communication Equipment). The connection is made via a 9-pin DSUB socket (female).

Pin	Signal	Description
1	DCD	Data Carrier Detect (NC)
2	TXD	Transmitted Data*
3	RXD	Received Data*
4	DTR	DTE Ready
5	GND	Signal Ground*
6	DSR	DCE Ready
7	CTS	Clear to Send
8	RTS	Ready to Send
9	RI	Ring Indicator (NC)

* Required connections for basic communication.

Connection to PC

For connection to a standard PC (DTE, 9-pin male connector), a 1:1 extension cable can be used. A null modem cable is not necessary in this case.

Remote Control Mode (RTU)

Like the Ethernet variant, two RS232 modules can also be coupled directly to mirror inputs to outputs. For this, the modules must be connected via a null modem cable (crossed lines) or a suitable transmission link (e.g., radio modems).
